Gap/pores in membrane that selectively allows particular materials to pass in/out of cell; not as selective as carrier protein.
Only allows one particular type of molecule to cross.
Recognition protein that is activated when selectively blinded to a ligand.
Protein that has carbohydrate molecules attached; Aids in cell recognition.
Found on inner/outer surface of lipid bilgier, and can be attached to internal/external surface of an integral protein. Acts as digestive enzymes to break down nutrients to sizes that can pass through cells/bloodstream.
Movement of particles from an area of higher concentration to area of lower concentration; Substances such as lipid-soluble molecules or small molecules can move through w/o energy; Form of passive transport.
Difference in concentration of a substance across a space.
Diffusion of water through a semipermeable membrane; Occurs when there is an imbalance of solutes outside a cell compared to the inside of the cell.
Diffusion process used for substances that are to big to cross lipid bilayer; done with aid of specialised carrier protein/channel protein.
movement of substances across the membrane using energy from ATP; Occurs when substances moves across against its concentration gradient.
Process of cell ingesting material by enveloping it in a portion of its membrane, then pinching off that portion of membrane; The pinched off portion becomes an independent vesicle.
endocytosis of large particles; cell eating
brings fluid containing dissolved substances into a cell through membrane vesicles; cell drinking
Process of cell exporting material to ECF using vesicular transport.
